Jung Sooyeon and Jung Soojung are siblings that love each other very much. But what would happen if Sooyeon finds something about her sister that is supposed to remain a secret?"If you have a sister and she dies, do you stop saying you have one? Or are you always a sister, even when the other half of the equation is gone?" - Jodi PicoultThis story is based only on my imagination and I do not own anything except the story. PLEASE DO NOT PLAGIARIZE. ForewordCredit for the amazing poster and background: Experimental™ | Color Lab
